SolidWorks 2017 doesn't function / Drawing interface frozen

Hi,

I recently installed SolidWorks 2017 on my laptop.

The program doesn't function at all - I can't see the interface / planes and start drawingparts, the work area shows the initial SolidWorks logo.

Moreover - if I minimize the program and maximize it, it partly shows my desktop...

Screenshot attached.

Any idea?

P.S.

The problem existed in 2 different installation versions
